Lake Charles, La. (KPLC) — As temperatures swing from hot to cold, many people are wondering how their plants are coping with these sudden changes.
According to LSU AgCenter horticulturist Robert Turley, the fluctuating temperatures can trick plants into thinking it’s spring. “The temperature stimulates them, causing them to bloom, as if it’s spring,” Turley explained. If you’ve noticed pear trees starting to flower, this is likely the reason.
Turley reassured gardeners that there’s no need for concern just yet. “This is the time when we start seeing our first cold weather, so it’s a good time to prepare,” he said. He suggests moving plants into a garage or greenhouse if possible to protect them from the cold.
Greengate Garden Center advises that when temperatures drop to 35°F or lower for more than an hour, it’s time to take action. You should either bring your plants inside or add insulation, like mulch or pine straw, to help retain moisture.
Some plants actually benefit from the cooler weather. “For example, cool temperatures help enhance the color of satsumas, turning them from green to their normal ripe orange,” Turley noted.
However, tropical plants require extra care. “Plants like hibiscus and other tropicals can be moved to the garage. They might turn yellow and lose leaves, but they’ll survive until spring when they can be brought back outside,” Turley advised.
